manual m/t

I've been reading several bad experiences from owners who did the latest recall work for the clutch, and some advising to skip it completely.. I booked in my recall work to be done, but I've since been reading a lot of issues where the new PCM software they install puts the jeep into limp mode...

My 6MT has a throttle response delay especially in the city if I am on 2nd gear on get up and go and was wondering if pedal monster could fix it. Anyone tried it before? I don't want to tune, supercharge, V8 swap, buy another car etc. Appreciate any relevant inputs! :)
